Operation principle
These drag chains were specially developed to ensure the stae convevance of flexible cables and hoses in order to supply energy to mobile units on driling platforms. This mode of energy supply avoids the tangling of cables/hoses which can occur there as a result of high wind speeds. Energy supply can be catered for on a made-to-measure basis for each case, using standard components. The chain bands and the stays which take up the supply cables are made of stainless steel which is adapted to requirements.

Stay Design
A tubular construction with dividers(if reguired) to separate the various types of hose/cable is used to carry the supply cable/hoses. Special stays on request. Please note the guidelines for laying cables/hoses in drag chains.

(Standard connection)
The screw-on surfaces of the connection angles can be positioned to the inside, the outside, or both sides(as shown) on the chain band. Connection brackets and usually located between the outer plates. Connection type and variant should be indicated on the order. Special construction chain connection angles on request.
Fixed point and drivera connection
In order to protect the supply cables/hoses from hot shavings and heavy dirt, the drag chains can be supplied with a stainless steel acid-proof spring band steel cover(thickness:0.4 0r 0.5mm, according to use).

Drag chains are used as vertically suspended chains with supporting struts in, for example, the machine industry in order to supply energy from control panels of adjustable height. The drag chain is run over gearwheels whose toothing corresponds to the chain pitch, and whose reference circle diameter is greater than or equal to the selected bending radius. It is driven by a separate geared motor or by a counterweight. The arrangement of this drag chain depends on the unit weight, and should be carried out by our technicans.

The drag chain is pulled by the connecting angles fastened to the chain bands. A simple steel constrution, which in most cases is made by the customer, is all that is needed to connect the drag chain and the mobile unit. Specially manufactured parts for higher speeds or a large amount of lateral play on request.

STEEL Cable Chains To equip special system With respect to the cable chain which has presently been developed, what is becoming the biggest point of problem was that it was very difficult to instal cable chain in the narrow space, along with prevention of phenomenon being drooped when long cable chain is installed. As result of installing expcriences obtained from installation and undertaking for several years, such point of problems has completely been settled. How to support Supporting Roller enumerated in the following, single ciroumference equipment, double circumference system, circular cable chain, etc. are our special know-how, and such special system instal1ing, undertaking requires technical consultation in advance, so you are asked to consult us with our technical part or business part in advance.
